Have you checked if the jumper is misplaced??
Are you using the power button on the case or on the board??
Did you connect the power headers properly???
Have you tried to power the board internally?
No beeps what so ever???
Yes everything is plugged in correctly and I have used external and internal power buttons. No not a single beep at all.. It will not read USB for the bios updates. No power coming to my pc whatsoever besides the on and reset L.E.D.s and the power L.E.D is red
Did the POST LED (marked II on Intel� Desktop Board DX79TO — Board component diagram ) show something when press power button? Dismount MB with CPU&memory from PC, place it on desk/paper and connect PSU, is there an action when press power button on MB?
I am having the exact same issue, I hope to contact Intel support soon. I hope they can help.
I think I may have been shipped a board with the 281 bios and it will not boot with this processor.
Unfortunately I don;t have the time or resources to seek a higher end processor to flash the bios.
I have taken this computer apart and re-seated everything and it still does not boot up at all. No error codes, no beeps, no numbers on the error code display on the board. Pretty hard to troubleshoot that.
